UCSD Tier 2 Event Log

Oct 27 2006

  • MIS Get CPUS script caused overload of the CE. The cron job was disabled and nominal loads were restored on the CE. During the problems we were able to keep from purging the CE Schedd queue which allowed us to delay, rather than cancel pending user jobs. The exception was for CDF jobs which are glide-ins and are best removed if you need to stop the actual job on the pool.
  • An update of the CA Certificates package on the GUMS server resulted in corrupting the GUMS VDT install. This required a full re-install of the GUMS infrastructure and about an hour of downtime. Existing jobs were not affected by authentication for new jobs was down during that time. The cause of the problem within pacman is still being investigated as of Nov 1 2006

  • Some NFS mounts were not properly refreshed from last weeks changes and at least one node had not gotten the proper auto.* files. These problems have been fixed
  • Applying OpenSSH? security patches to nodes and restarting OpenSSH?

Sept 20 2006

  • Power Cycles esf1 and patched it
  • Restarted most internal condor pools. There is a problem with the pools and schedd getting disconnected. Dan Bradley suggest upgrading to address a known bug related to network errors and schedd startd communication problems
